An AI tool just did what thousands of human developers couldn’t manage over 15 years — it found a hidden security flaw buried deep inside Linux, one of the most widely used operating systems on the planet. That single AI cybersecurity discovery set off a chain of questions about what else machines might be finding that people keep missing. And it wasn’t the only unsettling tech story to surface this week.
Key takeaways
- An AI tool called VEGA, built by Nebula Security, uncovered a Linux security bug that had gone undetected since 2011 — for 15 years.
- Google paid Nebula Security over $92,000 for the discovery, signaling how seriously the industry takes the find.
- Reporter Joel Feder was surrounded by four police cars after a license plate typo in the Flock system flagged his borrowed $155,000 car as stolen.
- The Pentagon launched a hacker training program paying just $22,500 a year, with no degree required — but trainees must repay costs if they fail.
- Accenture, a major contractor protecting US government networks, was hacked and had secret files stolen and offered for sale online.
AI Discovers a 15-Year-Old Linux Security Bug
Since 2011, a vulnerability had been quietly sitting inside Linux code — invisible to every developer, auditor, and security researcher who looked at it. Linux powers millions of machines worldwide, from personal computers to critical server infrastructure. For any malicious actor who knew about the flaw, it represented a potential backdoor to take full control of an affected machine.
Nobody found it. Until an AI did.
How Nebula Security and VEGA Changed the Game
Nebula Security deployed an AI tool called VEGA to systematically read through old computer code — the kind of exhaustive review that tends to defeat human attention spans. VEGA identified the flaw that had persisted, undetected, for a decade and a half. The bug is now fixed.
The implications run deeper than a single patch. This kind of AI cybersecurity discovery…
